Abstract
Biodiesel is produced in multi-stage batch reactors in which mass transfer is a rate limiting step. Mass transfer rates may be accelerated with ultrasound (US). In this paper, the performance of continuous flow US reactors, a Rosett US cell reactor, and a batch US reactor are compared to a conventional mechanically stirred batch reactor. The Rosett cell reactor combines acoustic cavitation and turbulence and achieved biodiesel yields greater than 90% in 5 min, whereas the same level of performance in the conventional reactor took more than 90 min. The most significant result of this work lies in achieving biodiesel yields greater than 90% after a single passage of the reagents in a continuous flow reactor in the presence of pulsed ultrasound. This corresponds to a reaction time of 18 s and a rate 300 times faster than the conventional process.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
